+
+Overview
+===========
+
+ESP32-PICO-KIT-1 is an ESP32-based development board produced by `Espressif <https://espressif.com>`_.
+
+The core of this board is `ESP32-PICO-V3 <https://www.espressif.com/en/products/socs>`_ - a System-in-Package (SiP) module with complete Wi-Fi and Bluetooth functionalities. Compared to other ESP32 modules, ESP32-PICO-V3 integrates the following peripheral components in one single package, which otherwise would need to be installed separately:
+
+- 40 MHz crystal oscillator
+- 4 MB flash
+- Filter capacitors
+- RF matching network
+
+This setup reduces the costs of additional external components as well as the cost of assembly and testing and also increases the overall usability of the product.
+
+The development board features a USB-to-UART Bridge circuit which allows developers to connect the board to a computer's USB port for flashing and debugging.
+
+All the IO signals and system power on ESP32-PICO-V3 are led out to two rows of 18 x 0.1" header pads on both sides of the development board for easy access. For compatibility with Dupont wires, all header pads are populated with two rows of male pin headers. 
+
+.. note::
+
+    ESP32-PICO-KIT-1 comes with male headers by default.
+
+ESP32-PICO-KIT-1 provides the users with hardware for development of applications based on the ESP32, making it easier for users to explore ESP32 functionalities.

+
+==================  =================================================================================================================================
+Key Component       Description
+==================  =================================================================================================================================
+ESP32-PICO-V3       Standard ESP32-PICO-V3 module soldered to the ESP32-PICO-KIT-1 board. The complete ESP32 system on a chip (ESP32 SoC) has been integrated into the SiP module, requiring only an external antenna with LC matching network, decoupling capacitors, and a pull-up resistor for EN signals to function properly.
+
+LDO                 5V-to-3.3V Low dropout voltage regulator (LDO).
+
+USB-to-UART bridge     CP2102N, single-chip USB-to-UART bridge that offers up to 3 Mbps transfers rates.
+
+Micro USB Port      USB interface. Power supply for the board as well as the communication interface between a computer and the board.
+
+5V Power On LED     This red LED turns on when power is supplied to the board. For details, see the schematic in `Related Documents`_.
+
+I/O Connector       All the pins on ESP32-PICO-V3 are broken out to pin headers. You can program ESP32 to enable multiple functions, such as PWM, ADC, DAC, I2C, I2S, SPI, etc. For details, please see Section `Pin Descriptions`_.
+
+BOOT Button         Download button. Holding down **Boot** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port.
+
+EN Button           Reset button.
+==================  =================================================================================================================================

+
+供电选项
+---------
+
+开发板提供以下三种供电方式，可任意选择一种：
+
+* Micro USB 供电（默认）
+* 5V/GND 管脚供电
+* 3V3/GND 管脚供电
+
+.. warning::
+
+    上述供电方式只能选择一种方式，不能同时选择，否则可能会损坏开发板和/或电源。
+
+
+管脚描述
